Introduction

ASTM A387 Grade 11 Class 2 steel plate is a high-quality alloy used primarily in the fabrication of pressure vessels and boilers. Known for its excellent heat resistance and durability, this steel plate is a popular choice in industries such as oil and gas, petrochemical, and power generation. At Sai Steel & Engineering Company, we pride ourselves on providing top-grade ASTM A387 Grade 11 Class 2 steel plates to meet the stringent requirements of our clients.

Description

ASTM A387 Grade 11 Class 2 steel plate is a chromium-molybdenum alloy designed to operate in elevated temperature environments. The addition of chromium provides enhanced resistance to oxidation and corrosion, while molybdenum increases strength and toughness. This combination makes the steel highly suitable for use in harsh conditions where both strength and resistance to thermal fatigue are critical.

Chemical Composition:

• Chromium (Cr): 1.00 - 1.50%
• Molybdenum (Mo): 0.45 - 0.65%
• Carbon (C): 0.05 - 0.17%
• Manganese (Mn): 0.30 - 0.60%
• Silicon (Si): 0.50% max
• Phosphorus (P): 0.035% max
• Sulfur (S): 0.035% max

Mechanical Properties:

• Tensile Strength: 70,000 - 90,000 psi
• Yield Strength: 40,000 psi min
• Elongation: 18% min in 8 inches
